hey all. I need your help if you please.
I am entering a dynamic data into excel sheet from a textbox.
the problem is that it enters letter by letter in every cell.
thanks in advance

What I have tried:

function bntEnterData_callback(hObject,eventdata,handles)
val1 = get(handles.txt1,'string'));
val2 = get(handles.txt2,'string'));
val3 = get(handles.txt3,'string'));
values = [ val1 val2 val3]
filename= 'try.xls';
sheet= 1;
xkRange= 'A2';
xlswrite(filename,values,sheet,xlRange);
